Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional bracket structure with multiple components and rivets is used, then the structural strength and stability are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple separate components (bracket, arm holder frame, arms, extension strips) into a single integrated elastic metal bow strip. This merging eliminates the need for rivets and assembly operations, reducing device complexity while maintaining structural integrity through the continuous elastic material design.
Solution Approach 2:
The patent uses an elastic metal bow strip that functions as a composite structure, integrating the functions of multiple rigid components into a single flexible element. This composite approach allows the structure to maintain strength while eliminating complex joints and connections.
2Stability of the object's composition
If a conventional bracket structure with multiple components is used, then the structural stability is improved, but the ease of manufacture and assembly are worsened
Solution Approach 1:
The patent merges multiple manufactured components into a single elastic metal bow strip that can be produced as one piece through forming operations. This eliminates the need for separate manufacturing of brackets, arms, and connection elements, significantly improving ease of manufacture while maintaining structural stability.
Solution Approach 2:
The patent extracts the complex bracket assembly from the traditional design and replaces it with a simplified elastic bow strip. This extraction removes unnecessary components and assembly steps, making manufacturing easier while the elastic properties of the strip provide the needed structural stability.
3Reliability
If a conventional bracket structure with multiple rivets is used, then the structural integrity is improved, but the loss of time in assembly and the manufacturing cost increase
Solution Approach 1:
The patent combines multiple riveted components into a single elastic metal bow strip, eliminating the need for rivet assembly operations. This merging reduces assembly time to minimal steps while the continuous material structure maintains structural integrity without requiring mechanical fasteners.
Solution Approach 2:
The elastic metal bow strip is designed to be self-supporting and self-securing, eliminating the need for external fasteners like rivets. The strip's elastic properties allow it to maintain structural integrity through its own material characteristics rather than requiring additional joining operations.
